This study investigated the data provided to users through the interface of level 3 autonomous cars under the SAE standard. Among the data on autonomous-car driving to be provided to a user, those that are commonly provided were grouped based on the OEM manual. Data significance was prioritized in the vehicle-to-vehicle and vehicle-to lane distance maintenance, lane change, low-speed driving, branch road driving, and right turn(intersection) scenarios. The prioritized data were combined into different groups under three methods, and the “quantities of data” on the interface were compared by changing the combinations. Images were provided to the 33 experiment participants through the center fascia inside the car. On average, the perception time was in the 5 s range, the GSR(peak) was in the 2 μs range, the survey was in the 5 s range, and the perception rate was in the 70 % range. Such results can be a useful reference for designing future autonomous-car driving data provision. |
